Valves & Actuation

Georg Fischer Type 567: Manual with Lever - PVC \ EPDM
Georg Fischer Type 567: Manual with Lever - PVC \ EPDM

The Type 567 is a wafer style butterfly valve rated for pressures up to 150 psi and temperatures of up to 140° F for PVC and 176° F for CPVC, also available in polypropylene and PVDF. Better chemical compatibility is achieved because the inner body is the same material as the piping. The Type 567/578 Butterfly valves have a unique eccentric design that means the disc is not in contact with the seal in the open position. The result is less wear and operating torques half that of previous models. Georg Fischer double eccentric butterfly valves require approximately 50% less operating torque than boot-style competitive valves. Lever and gear operators are both available. In the lever version, the opening angle is clearly indicated on the index plate.

Hayward True Union Ball Valves are superior performers. A fine-pitch seal retainer thread allows for accurate compensation for seat wear. Reversible seats make it easy to get a damaged valve back in service. Should the seats become damaged, they only need to be removed, turned over, and re-installed to put the valve back on line. These valves feature a double o ring stem seal for twice the leakage protection of valves with only a single stem seal. Hayward’s manual True Union Ball Valve has been designed so that it can easily be converted to an automated valve in the field. To do this, just remove the compression fit handle and install an actuator mounting bracket.
